+  # It runs early (order 200) so other specMaps can see the enable flags.
+  #
+  # How it works:
+  # 1. For each spec, extract its name (removing -lazy suffix if present)
+  # 2. Check if there's a corresponding cats.<name> toggle
+  # 3. Set spec.value.enable based on the cats toggle (default: true)
+  # 4. This allows specs to be conditionally included based on config.cats settings
+  #
+  # Example: If config.cats.python = false, then specs.python.enable = false
